// Hadronic Process: Nuclear De-excitations
// by V. Lara (May 1998)
//
// Modif (03 September 2008) by J. M. Quesada for external choice of inverse 
// cross section option
//
// Modif (30 June 1998) by V. Lara:
//      -Using G4ParticleTable and therefore G4IonTable
//       it can return all kind of fragments produced in 
//       deexcitation
//      -It uses default algorithms for:
//              Evaporation: G4StatEvaporation
//              MultiFragmentation: G4DummyMF (a dummy one)
//              Fermi Breakup model: G4StatFermiBreakUp
//
// Modif (03 September 2008) by J. M. Quesada for external choice of inverse 
// cross section option
// JMQ (06 September 2008) Also external choices have been added for 
// superimposed Coulomb barrier (if useSICBis set true, by default is false)
